Crash on Mac

I figured this out from one of my users. If you create a combobox
without specifying a value and then call GetValue(), wx coredumps.
It works fine on Windows and Linux.

cb=wx.ComboBox(panel, -1, style=wx.CB_DROPDOWN, choices=["1", "2", "3"]
print cb.GetValue()

The above coredumps. Adding "" as a parameter after -1 fixes it.

I'll take a look.

Here is a whole bunch more stuff to do with ComboBoxes. 100% reliable
crashes on Mac, and some platform differences on Windows and Linux.
I have attached the test code.

Mac output:

cb1: GetSelection() = -1
cb1: GetValue() = ''
cb2: GetSelection() = -1
cb2: GetValue() = ''
cb3: GetSelection() = -1
Segmentation fault

Windows outuput:

cb1: GetSelection() = -1
cb1: GetValue() = ''
cb2: GetSelection() = -1
cb2: GetValue() = ''
cb3: GetSelection() = -1
cb3: GetValue() = ''
cb4: GetSelection() = -1
cb4: GetValue() = ''
cb5: GetSelection() = 2
cb5: GetValue() = '3'
cb6: GetSelection() = -1
cb6: GetValue() = ''
cb7: GetSelection() = -1
cb7: GetValue() = ''
cb8: GetSelection() = 2
cb8: GetValue() = '3'

Linux output:

cb1: GetSelection() = -1
cb1: GetValue() = ''
cb2: GetSelection() = -1
cb2: GetValue() = ''
cb3: GetSelection() = -1
cb3: GetValue() = ''
cb4: GetSelection() = -1
cb4: GetValue() = ''
cb5: GetSelection() = -1
cb5: GetValue() = '3'
cb6: GetSelection() = -1
cb6: GetValue() = ''
cb7: GetSelection() = -1
cb7: GetValue() = ''
cb8: GetSelection() = -1
cb8: GetValue() = '3'
